NOTE
• Terminal JOG input specifications (pulse train input or contact input) can be selected with Pr.291. When changing the setting
value, be careful not to change the terminal JOG input specifications. (Refer to
• Install a meter between terminals FM and SD after changing the Pr.291 setting value. During output the pulse train via terminal
FM (voltage output), be careful that voltage is not added to terminal FM.
• The meter cannot be used for the pulse input in a source logic type.
• If the All parameter clear is performed when the high-speed pulse train output is selected (Pr.291 = "10, 11, 20, 21, or 100"),
the output via terminal FM is changed from high-speed pulse train output to the voltage output because the Pr.291 setting
resets to the initial value "0". To perform the All parameter clear, remove the device connected to terminal FM first.

Adjustment of terminal FM/CA and terminal AM

The output via terminal FM/CA or terminal AM corresponding to the full-scale value of a meter can be adjusted (calibrated) on
the operation panel or the parameter unit.

 Terminal FM calibration (C0 (Pr.900))
• The output via terminal FM is set to the pulse output. By setting C0 (Pr.900), the meter connected to the inverter can be
calibrated by parameter setting without use of a calibration resistor.
